Yeh it is, I disabled vertical synch (I usually have it on in most games and don't notice the drain) and I was able to set a lot of settings to high, of course majority of physics is still a problem, I should really upgrade my GFX and probably CPU, and add more RAM, I'll do that when the time comes.
What really does stand out in this game is the detail of the monsters, seriously, some really creep me out, and that doesn't happen often.
While on my way to some quest point I encountered an Alghoul, fucking shit freaked me out, and was 7 levels ahead, had to fucking run away for now, I'll get you bastard, I'll get you !
The combat mechanics are great, but the thing I really love is investigation.
This part of the game is superb.
Crafting is also great, you can get multiple schematics for the same item which only improves the crafted item up to master level, very interesting and I like it.
I found it ironic that a small studio makes a much better game than the top studios in the world. Probably because they have to count every penny. And to think they started with Neverwinter Nights engine
